Balancing Your Pool Water – Calcium Hardness
Understanding Calcium Hardness (CH)
Don’t be Afraid of Calcium!
Pool water with a calcium level above 1,000 ppm may become cloudy and if left long enough will form scale on pool surfaces and fittings. CH below 200 ppm can corrode pool equipment. In plaster pools it may result in pitting or etching problems. You need calcium for balanced pool water.
What is Calcium Hardness (CH)? CH is a measure of dissolved calcium in water.
What does it do?
- Protects plaster pool surfaces
- Protects heaters (heat exchangers)
- Minimizes foaming

Cal Hypo as a daily sanitizer?
Up to 1,000 ppm calcium levels are OK!
Maintain clear water by simply adjusting TA to lower end of range (60 – 80 ppm).
